Material Carbon reinforced epoxy
This material is known for its high specific stiffness and strength, given by carbon fibres. The material has an advantageous combination of good mechanical properties and low weight.

The properties of the material vary depending on the content and orientation of the fibres.
It is used for very stiff and light structures within sport equipment, aerospace, medical equipment (protheses) and prototyping.

The carbon fibres can be woven into mats, which can be pressed into 3-dimensional shapes, and then plastic is added. The most used processes are manual fibre moulding, RTM, filament winding, pultrusion, and autoclave injection.
